Machine interoperability: OPC UA/DDS Gateway

Host: Vienna University of Technology (TUWIEN)Institute of Computer Aided Automation.

  • Main supervisor: Prof. Wolfgang Kastner, k@auto.tuwien.ac.at (contact person)
  • Co-supervisor: Prof. Gerhard Fohler, fohler@eit.uni-kl.de

Objectives:

  1. Increasing the interoperability of machines, allowing larger and more flexible systems and access to data at all levels for data analytics.
  2. Developing a distributed and Service Oriented gateway capable of bridging OPC UA and DDS, the most widespread standards for interoperability.

Expected Results:

  • Definition of an architecture, technology stack, and the mappings necessary to support the exchange of information and functionality between data-centric DDS and object-oriented OPC UA systems.
  • Design and implementation of a vendor-neutral and standard bidirectional gateway for information exchange and interoperability between DDS and OPC UA.
  • Algorithms necessary to introduce guarantees for scalability, security, and reliability in a Fog environment within the context of middleware applications; their development and evaluation.

Planned visits and collaboration:

  • ABB (Dr. Magnus Larsson): Evaluate the OPC UA/DDS gateway on the ABB use case.

Description:

The aim of this PhD project is to research and implement a distributed and service oriented bi-directional gateway bridging OPC UA and DDS. Specifically, this would involve the definition of an architecture, technology stack, and the mappings necessary to support the exchange of information and functionality between the two. This includes allowing for the execution, discovery, and updating of services, operations, and information in both systems and on the gateway itself. Algorithms necessary to introduce guarantees for scalability, security, and reliability in a fog environment within the context of middleware applications will need to be developed and tested for their impact on hybrid DDS and OPC UA systems.
